So Last night Ocacian was having trouble with some roof panels refused to place. Saying "Too Far underground" thats a cryptic message that usually means you dont have enough foundations.

After about a 30 minutes i figured out the problem and Fix.

He has a large house, multiple stories. The entire bottom is Foundations. Which SHOULD allow all the upward building u can desire.

To get to the top level he has stair cases, like your supposed to.

What i found, for reasons only Conan Knows, the "open" areas where staircases go up to the next level of his house, were glitching the placement. it was only ones DIRECTLY below and ALL the way to the ground floor. So the floor just under the top floor was all solid where the roof panels were being placed, but 2 stories down, it happened a staircase lined up with the roof panel.

When i placed ceilings and moved the staircase, i was able to place the roof panels.

Dumb dumb dumb. Thats all i gotta say.

I did post a bug report on the conan forums for this issue.
